First single-core MPU with MIPI CSI-2 camera interface and advanced audio features

The embedded market needs more powerful, but less power-hungry, artificial intelligence (AI) solutions that can be deployed at the edge, where power consumption is often paramount. AI solutions often require advanced imaging and audio capabilities typically only found on more capable multi-core microprocessors which, unfortunately, also consume significantly more power. To provide developers with access to these higher performance peripherals without sacrificing power consumption, Microchip Technology Inc. today announces the MPU based on Arm Cortex A7 SAMA7G54 operating up to 1 GHz. The SAMA7G54 includes both a MIPI CSI-2 camera interface and a traditional parallel camera interface, allowing developers to design low-power stereo vision applications with more accurate depth perception.

Microchip is committed to maintaining the lowest power MPU portfolio in the market. The SAMA7G54 extends this low-power trend into the 1 GHz performance class of Linux-compatible MPUs by providing flexible low-power modes, as well as voltage and frequency scaling. When paired with Microchip’s new MCP16502 power management integrated circuit (PMIC), this MPU allows embedded designers to fine-tune their end application to achieve the best overall power consumption versus performance, while also optimizing the lowest overall system cost. The MCP16502 is supported by Microchip’s core Linux distribution for the SAMA7G54, allowing easy entry and exit from available low-power modes, as well as support for dynamic voltage and current scaling. frequency.

“The SAMA7G54 offers designers a low-risk path to developing power and performance-optimized AI solutions for edge deployment,” said Rod Drake, vice president of the 32-bit MPU business unit at Microchip. “Designers can now create high-performance, audio-centric visuals AI applications without having to use multi-core MPUs with much higher power consumption.

For audio applications, the device incorporates enhanced audio features such as four I2Digital S audio ports, an 8-microphone network interface, an S/PDIF transmitter and receiver, and a stereo four-channel audio sample rate converter. It is equipped with multiple microphone inputs for better source localization to improve the performance of the smart speaker or video conferencing system.

The SAMA7G54 also incorporates Arm TrustZone technology with secure boot, secure key storage and cryptography with acceleration and more. Customers can work with Microchip security experts to assess their security needs and implement the right level of protection for their design.
